FIELD OF THE INVENTION

The present embodiments described herein relate generally to mops and, more particularly, to a pad mop or mop head attachment configured to hold and dispense a roll of cleaning material.

BACKGROUND OF THE INVENTION

Wet mops are used to clean wood, stone and artificial floor surfaces in order leave them cleaner than by just sweeping or vacuuming the floor surface. In its basic form, a wet mop consists of an attachment device at the end of a pole or handle to which an absorbent element such as a rag can be attached and then submerged into a pail with water or cleaning solution. The wet rag is wrung out and then used to apply the water and/or a cleaning solution to the floor surface. The mop is used to clean and dislodge debris from the floor surface. The mop is then re-submerged in the water/cleaning solution to rinse the mop. Once rinsed, the mop is again wrung out and the mop is then used to clean another section of the floor surface being cleaned.

Traditional mops consist of a pole/handle and at the bottom end of the pole/handle absorbent element such as cord-like strands, cloth fiber-like strands, or sponge connected to the pole/handle for cleaning. Some wet mops have a “wringing” device attached to the mops to make wringing out the absorbent element easier and more hygienic/cleaner after rinsing the mop in the water/cleaning solution. (See U.S. Pat. Nos. 6,745,429; 6,625,838; 6,477,731; 5,675,858; 6,108,848; Re37,415; 6,550,094; and 6,892,415).

While the problems associated with “wringing-out” such wet mops have been lessened by the introduction of “wringing-out” devices incorporated into the mops, the other problem, of requiring a constant refreshing of the water/cleaning solution in order not to use dirty water/cleaning solution to clean the floor surface, persists.

Pad-style mops have been introduced to address this issue. (See U.S. Pat. Nos. 7,163,349; 7,144,173; 7,028,364; 6,986,619; 6,986,616; 6,893,180; 7,144,173; 7,028,364; 6,979,371; and the like.) Pad mops generally consist of two primary elements: 1) a pole/handle with a flat square or rectangular “mop pad” at the bottom end and 2) specially designed “absorbent pads” that attach to the “mop pad” and which are needed in order to “mop” the floor surfaces. The rectangular “mop pad” is connected to the pole/handle via a universal joint. This universal joint connection enables the “mop pad” to be turned in various positions in order to get into tight places and under furniture.

“Pad mops” require specially designed “absorbent pads” that attach to the “mop pads” via various securing devices. These absorbent pads act as the “mop” and can be changed as they become soiled while mopping the floor surface. While pad mops eliminate the need for “wringing” devices, one of the main drawback of conventional pad mops tend to be that as one uses a “pad mop” on a floor surface, one must constantly and manually replace the soiled “absorbent mop pads”, thus coming in physical contact with the soiled pads and cleaning solution in order to replace them with a new “absorbent pad”.

Thus, it is desirable to provide an improved pad mop.

SUMMARY OF THE INVENTION

The embodiments and examples provided herein are generally directed to a pad mop and a mop head attachment device for a pad mop.

The novel pad mop and mop head attachment device have been disclosed and described in U.S. Provisional Application Nos. 61/732,243, 61/789,425, and 61/831,086, which are incorporated herein by reference.

Turning to the figures, the various embodiments provided herein are generally directed to a pad mop with a mop head attachment device. As shown in FIG. 1, the pad mop comprises a mop handle 1, a mop head 13 coupled to the handle 1 and a mop pad 13′ coupled to the mop head 13. The mop head 13 and mop pad 13′ are generally square or rectangular shaped. In a first embodiment, the mop head attachment 14 attaches itself to the mop head 13 and mop pad 13′ (see also FIG. 2) via four attachment points 15 formed in the top of the mop head 13. The mop has a U-Joint 2 to which the mop handle 1 is attached and which is affixed to the top of mop head 13.

The mop head attachment 14 comprises a casing that is open at both ends and configured to fit around the mop head 13 and mop pad 13′. As depicted, the casing of the attachment 14 includes a bottom, opposing sides extending up from the bottom, and two top attachment lids A and B hinged at hinges 8 to individual ones of the opposing sides to allow the top attachment lids A and B to open outwards so the mop head 13 and mop pad 13′ can be placed within the casing of the mop head attachment 14. The two lids A and B of the top of the casing of the mop head attachment 14 are releasably attachable to the four attachment points 15 formed in the top of the mop head 13 via casing connectors 16. The casing connectors 16 and attachment points 15 are configured to releasably interlock with one another.

On the top of one lid B there is a cleaning material holder that comprises a holder 6 and a holder top 5 that is hingedly connected at a hinge 3 to the holder 6. On the other lid A is a cleaning material take up mechanism comprising a feeder 19 and a gear teeth shaft 9.

A cleaning material roll 4 is positionable within the cleaning material holder 6 and holder top 5. Cleaning material 18 from the cleaning material roll 4 extends out the cleaning material holder 6 and around the bottom of the mop head attachment 14 and up and around and into the feeder 19. The feeder 19 feeds the cleaning material 18 into the gear teeth shaft 9 that is turned by a gear knob 10. As the knob 10 is turned, the gear teeth shaft 9 pulls the cleaning material 18 up and out through a hatch 20 where it can then be cut off by a cleaning material cutter knife 11 which is slid across the length of the cleaning material hatch by a cutter handle 12. The cutter handle 12 is on a lever 17A that is hinged at a hinge 17 to a gear casing 22 allowing for the cleaning material 18 to be fed through and out of the cleaning material hatch 20 before cutting.

The cleaning material roll 4 is mounted on a four or six sided spindle 21 so that a “stop” lever (not shown) can be engaged to stop the cleaning material roll 4 from rolling and feeding the cleaning material 18 out of the cleaning material holder 6, or disengaged to allow the cleaning material roll 4 to roll and dispense the cleaning material 18 as the gear knob 10 of the gear teeth shaft 9 is turned to replace the soiled cleaning material with clean cleaning material 18 coming from the cleaning material holder 6.

The gear teeth shaft 9 will have a gear mechanism that will allow the knob 10 and gear teeth shaft 9 to move only in the direction that will pull the cleaning material 18 up and out the cleaning material hatch 20, but will not go in the opposite direction. This will allow one to move the cleaning material 18 out of the cleaning material holder 6, around the bottom of the mop head attachment 14, up to the cleaning material feeder 19, and then tighten the cleaning material 18 once one engages the “stop” lever of the cleaning material holder 6 on the square or hexagonal cleaning material spindle 21.

In another embodiment shown in FIG. 3, the mop head attachment 14′ attaches itself to the mop head 13 using the four attachment points 15 formed in the top of the mop head 13. The mop head attachment 14′ comprises is a flat rectangular casing with a rectangular hole O in the middle of the casing (See FIG. 4) so that it can be slipped on top of the rectangular mop head 13 and connected to the top of the mop head 13 via four casing connectors 16 to the four mop attachment points 15.

On the top of one side B of the casing of the attachment 14′ is a cleaning material holder that comprises a holder 6 and a holder top 5 that is hinged at a hinge 3 to the holder 6. On of another side A of the casing of the attachment 14′ is a cleaning material take up mechanism comprising a feeder 19 and a gear teeth shaft 9.

The cleaning material roll 4 is positionable within the cleaning material holder 6 and cleaning material 18 extends out from the cleaning material holder 6 and over a casing roller BB and down around the bottom of the mop head 13 and mop pad 13′ and back up and around another casing roller AA on the opposite side of the attachment 14′ and into the feeder 19. The feeder 19 feeds the cleaning material 18 into the gear teeth shaft 9 that is turned by a gear knob 10. As the knob 10 is turned, the gear teeth shaft 9 pulls the cleaning material 18 up and out through a cleaning material hatch 20 where it is then cut off by a cleaning material cutter knife 11 which is slid across the length of the cleaning material hatch 20 by a cutter handle 12. The cutter handle 12 is on a lever 17A that is hinged at a hinge 17 to a gear casing 22 allowing for the cleaning material 18 to be fed through and out of the cleaning material hatch 20 before cutting.

The cleaning material roll 4 is mounted on a four or six sided spindle 21 so that a “stop” lever (not shown) can be engaged to stop the cleaning material roll 4 from rolling and feeding the cleaning material 18 out of the cleaning material holder 6, or disengaged to allow the cleaning material roll 4 to roll and dispense the cleaning material 18 as the gear knob 10 of the gear teeth shaft 9 is turned to replace the soiled cleaning material with clean cleaning material 18 coming from the cleaning material holder 6.

The gear teeth shaft 9 will have a gear mechanism that will allow the knob 10 and gear teeth shaft 9 to move only in the direction that will pull the cleaning material 18 up and out the cleaning material hatch 20, but will not go in the opposite direction. This will allow one to move the cleaning material 18 out of the cleaning material holder 6, around the bottom of the mop head 13 mop pad 13′, up to the cleaning material feeder 19, and then tighten the cleaning material once one engages the “stop” lever of the cleaning material holder 6 on the square or hexagonal cleaning material spindle 21.

Turning to FIGS. 5 and 7-10, another embodiment is provided herein that is generally directed to a pad mop with a mop head attachment device. As shown in FIG. 5, the pad mop 200 comprises a mop handle 201 and a mop head 210 coupled to the handle 201. The mop head 210 includes a mop head base 211 and a mop pad 213 coupled to the mop head base 211. The mop head 210 and pad 213 are preferably generally square, rectangular or quadrilateral in shape. A mop head attachment 214 attaches itself to the mop head 210 and mop pad 213. The mop head has a U-joint 202 to which the mop handle 201 is attached and which is affixed to the top of mop head base 211.

The mop head attachment 214 comprises a casing that is open at both ends and configured to fit around the mop head 210 and mop pad 213. As depicted, the casing of the attachment 214 includes a bottom 216 and opposing sides 217 and 219 extending up from the bottom 216 that curve over or wrap around the edge of the mop head 210 and mop pad 213 and point inwardly toward the U-Joint 202.

Attached to the top of one side 219 of the casing is a cleaning material holder 206 that comprises a tubular casing. The cleaning material holder 206 can, as shown in FIGS. 11 a and 11 b, include a lid 205 hingedly coupled at a hinge 203 to the holder 206.

A cleaning material or cleaning material roll 204 is positionable within the holder 206. Individual paper or cleaning material sheets 218 extend from the cleaning material roll 204 out of the cleaning material holder 206 through a slot 207 and are pulled from the holder 206 until posts 220 projecting upward from the side 219 of the mop head attachment 214 and penetrate through and engage slits 222 in the cleaning material sheets 218. The slits 222 are preferably V-shaped slits configured to engage the posts. The sheet of cleaning material 218 is wrapped down around the holder side 219 of the mop head attachment 214, around the bottom 216 of the mop head attachment 214 and up and around the other side 217 of the mop head attachment 214 and secured into capture details 215 formed in the top of the mop base 211. Alternatively, there are posts extending from the side of the mop head attachment 214 opposite the cleaning material holder 206 that penetrate through V-slits in the other end or leading edge of the sheet of cleaning material 218.

Referring to FIG. 6 a, a roll of cleaning material 204 is shown partially unrolled wherein the cleaning material 204 includes a repetitive pattern of perforations 224 that divides the cleaning material 204 into a multiple or plurality of individual sheets of cleaning material 218. The slits 222 are form on each side of the perforation 224 to engage posts 220 extending from the sides 217 and 219 of the mop head attachment 214.

In FIG. 7, a sheet 218 of the cleaning material 204 is shown wrapped around the mop head attachment or dispenser assembly 214. The cleaning material 204 is secured against tearing at the perforation 224 by the posts 220 and slits 222 arrangement. The posts 220 penetrating the slits 222 secure the sheet 218 of cleaning material 204 during cleaning. The loose end of the sheet of cleaning material 218 is secured in the capture details 215 of the mop head base 211 before the mop 200 is used for cleaning. FIG. 8 provides a partial exploded view of the dispenser assembly or mop head attachment 214 that is attachable to the mop head 210 and pad 213, and the roll of cleaning material 214 spaced apart from the mop head attachment 214 and in its wrapped around configuration.

In operation, as shown in FIGS. 9A-9D, the used sheet 218′ of cleaning material 204 is first extracted from the capture details 215 and unwrapped from the dispenser assembly 214 and lifted off of the posts 220. Next, the cleaning material is pulled from the supply roll 204 until a new sheet of cleaning material 218 is secured at the slits 222 along its leading edge 221 to the posts 220. The old or used sheet of cleaning material 218′ is then tensioned and pulled, resulting in the separation of the used sheet of cleaning material 218′ from an unused sheet 218 of cleaning material 204 at the perforation 224.

After removal of the used sheet of cleaning material 218′, a short length of an unused or new sheet of cleaning material 218 remains exposed as shown in FIG. 10. This short length of cleaning material 204 is easily gripped and pulled at the next time a user desires to clean. To clean, the cleaning material 204 is pulled out until the slits 222 along its trailing edge engage the posts 220 along the side 219 of the mop head attachment 214. The sheet 218 is wrapped around the mop head attachment 214 and secured in the capture details 215 and the slits along the leading edge engage posts on the opposing side 217.

Referring to FIGS. 6 b and 6 c, alternative embodiments of rolls of cleaning material are shown to include a repetitive pattern of perforations 224 and one or more elongate slits 225 coextensive with the perforations 224 that divides the roll of cleaning material into a multiple or plurality of individual sheets of cleaning material 218. The sheets of cleaning material 218 include a second repetitive pattern of one or more elongate slits 223 formed adjacent the perforations 224 and slits 225 along the leading edge of the sheet of cleaning material 218. Instead of engaging a plurality of posts 220 extending from the sides 217 and 219 of the mop head attachment 214, the elongate slits 223 and 225 engage a tooth or one or more teeth extending up from one or more of the sides 217 and 219 of the mop head attachment 214. Each tooth can be formed as a solid member extending between one or more of the posts 220 shown in FIG. 5.

As shown if FIGS. 6 b and 6 c, the cleaning material moves in the direction of the arrows as a user of the mop 200 pulls the material to tear off a dirty or used sheet of cleaning material 218′. To tear off the dirty or used sheet of cleaning material 218′, the one or more elongate slits 225 along the perforations 224 catch or engage the one or more elongate teeth. When the sheet of cleaning material 218 gets dirty as the diagonal lines on sheet 218′ indicate, the user lifts the sheet of cleaning material 218′ up from the long tooth or teeth that is holding the sheet of cleaning material 218′ in place via the slit 225 in line with the perforations 224, then pulls the cleaning material to the right or forward on to the next slit 223 adjacent the perforations 224 to hold the material in place while the user tears off the dirty or used sheet of cleaning material 218′ along the perforations 224.

In an alternative embodiment, shown in FIGS. 11A and 11B, the cleaning material holder 206 is formed in a recess formed in a bumper 212 extending from the side 219 of the mop head 214 attachment. As shown, the cleaning material holder 206 includes opposing roll holder arms 209 extending upward from the bumper 212.
